Evaluate y5 + x(-7)<br> When x = 2, y = -5

Ymorist [56]

Answer:

Step-by-step explanation:

OK, first we turn the variables into into the actual values:

The equation will look like this:

(2)5 + (-5)(-7)

Now its easier to solve! Lets solve (2)5!

2 * 5 = 10

The equation looks like:

10 + (-5)(-7)

We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!

-5 * -7 = 35

Lets finish the rest:

10 + 35 = 45.

Hope this is correct and have a nice day!

Solve for the indicated variable

GrogVix [38]

Answer:

$X_1=\frac{YX_2}{X_2-Y} \\\\$

Step-by-step explanation:

$\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}$

First subtract the 1/x2

$\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}$

Next subtract the fractions on the left

$\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\$

Next Multiply by x1

$\frac{(X_1)X_2-Y}{YX_2}=1\\$

Next divide both sides by the remaining parts (not x1)

$X_1=\frac{YX_2}{X_2-Y} \\\\$
